I should have took puctures i just done mine lasy night to fit new oven and hob..... Anyway now you have this connected (i would have taken the connection from the back of the outlet) but yeh you can just put a 3 core 1.5mm t&e/flex into your new socket outlet and plug in the oven
go to grahams (plumbers merchant) get a toilet they sell one with the cistern pack fitted, tighten up 2 bolts bit multi kwik and flexi hose with isolator to the torbeck valve....job done 25 mins
board to cooker switch 6mm
cooker switch to cooker outlet 6mm
cooker outlet to unswiched socket or flex outlet can be done in 1.5mm as that is probably what is on your oven
ok heres how i would do it
the cooker switch with socket up where the tiling is from that 6mm cable to cooker outlet (to connect hob)
then a single socket if oven has plug, if not fit a flex outlet just incase your hob doesnt fit in because of surface box etc
if you had a gas hob there should...
